Factor out 8 and then facotr and u get
8/9(9x+1)(9x-1
Answer:
I believe it is they will weigh the same
Explanation:
Center of gravity is the axis on which the mass rotates evenly if I remember correctly from AP Physics
From Newton's second law:
a = F/mass
Therefore, acceleration of an object rolling a ramp would be:
a = g(sin theta) - friction coefficient (g) (sin theta)
The negative sine is due to the kinetic energy opposing the gravity
We are given that the friction coefficient is zero, the g is a constant = 9.8 m/sec and the acceleration is 2 m/sec^2
Substituting in the equation, we get:
2 = 9.8 sin(theta)
sin (theta) = 0.20408
theta = 11.7757 degrees
The direction of the angular velocity of the minute hand of a wall-clock is perpendicular to the wall and directed inwards.
The passenger slides away from the centre of the curve.
The angle θ which a cyclist should make with the vertical while taking a circular turn of radius r with velocity v given by
tan θ = v^2/rg
Sharper the curve, smaller is the radius and greater is the value of 0.
